Cookware & Bakeware · 8 specs
Direct Answer
Skillets and frying pans are measured across their top outer rim diameter (8", 10", 12", 14"), with flared sidewalls reducing the usable flat cooking base by approximately 2 to 2.5 inches relative to the nominal rim diameter.

Understanding Rim vs Base Area
Because skillet manufacturers measure pans by the top rim diameter, a 12-inch skillet provides 58% more cooking surface area than a 10-inch skillet (74.7 sq in vs 47.2 sq in). Choosing a 12-inch pan prevents crowding and steaming when searing proteins.
